I recall that many of the sh-coff tests on gcc-30 from CVS are failing
due to linker errors.  You really should look at the file 
gcc/testsuite/gcc.log for more details on the failures.  My experience
is that when the number is this high, they tend to cluster.  For example,
last week one VERY minor problem caused about 3600 failures for sparc-elf.
